TEM PORARY BINDER.

srncztrfcnrr'on forming art of Letters Patent No. 634,630, dated October 10, 1899.

1 Application filed May 10, 1899. Serial in. 716,199. (No model.)

To all whom it may concern:

Be it known that LFREDERIGK J. SCHLEEDE, a citizen of the United States, residing at Ann Arbor, in the county of Washtenaw, State of Michigan, have invented certain new and useful Improvements in Temporary Binders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form apart of this specification.

This invention relates to temporary binders and it consists in the construction and arrangernent of parts hereinafter fully set forth, and pointed'out particularly in the claims.

The object of the invention is to provide simple and efficient means for binding temporarily within the cover sheets of manuscript, music, book-pages, and periodicals in such manner as to enable all or any portion of the bound matter to be readily detached when desired. This object is attained bythe device illustrated in the accompanying draw ings, in which Figure 1 is a perspective view showing a cover provided with my improved binder, between the leaves of which a number of pages are bound. Fig. 2 is a perspective view of the cover, showing the parts in position to receive thepages to be bound therein. Fig. 3 is a perspective view of the Wire bindingstrand detached from the cover. Fig. 4c is an enlarged plan view of a portion of the back of the cover, showing a leaf or page upon the curved ends of the binding-strand and said ends detached from their engaging eyelets in the back of the cover. Fig. 5 is a transverse section as on line 5 5 of Fig. 1, parts being broken away.

Referring to the letters of reference, A designates a cover of any suitable size and construction provided with a flexible back B. Located in said back, at one side thereof, are the open eyelets a, and also located in said back opposite the eyelets a are the capped eyelets c.

D designates a single strand of wire having right-angled end portions b",which are curved in the arc of a circle and which stand in the ing wire therein.

v same plane, the end of each of said curved portions being provided on its outer face with an engaging hook c. This binding bail or strand is formed, preferably, of spring-wire, and it is inserted in the back of the hook by passing the end of the curvedportions 17' through the eyelets a from the 0utsid e,which will cause said curved end portions to stand within the cover of the book with their ends adjacent the eyelets c. The matter to be bound within the cover or binder is forced again st the sharpened free ends of the curved portions 1) of the binding-wire, whereby said matter is perforated, enabling the leaves or pages to be bound to he slipped upon said curved end portions, as shown in Fig. 4, in which 0 designates a page bound within the cover. After the leaves or pages have been placed upon the curved end portions of the binding-wire the free ends of said-curved portions are secured to the back of the cover-by springingthem into line with the eyelets c and passing them into said eyelets so that their hooks e will engage the shoulder of the eyelet and retain the curved ends of the bind- The normal position of the curved end portions b of the binding-wire causes'them to stand slightly out of alinement with the eyeletsc, so that it is necessary to spring the free ends of said curved portions sidewise in order to engage them in said eyelets, the spring of said curved portions servingto hold their'hooks e engaged with the eyelets after insertion therein. lVhen the cover is closed upon the bound pages, the straight portion of the binding-wire extends some distance from the back of the-book, as shown in Figs. 1 and 5, serving as a handle by means of-which the book may be carried.

When it is desired to detach a sheet from the binder, the curved end portions b are sprung sidewise, so as to disengage the hooks e from the eyelets, when said curved ends may be withdrawn from said eyelets and the page slipped therefrom, the free ends of the curved portions bein a ain engaged in the eyelets c in the back of thecovei s before described. The caps on the eyelets c prevent the ends'of the curved portions of the hinding-wire from protruding through the back of the cover, keeping said curved end portions always in place.

This device is simple and inexpensive, yet affords eilicient means for binding temporarily between covers manuscript pages or printed matter of any character in such manner as to preserve the matter bound and at the same time permit the ready insertion of a page or sheet or the Withdrawal of any page or part of the matter desired.

Having thus fully set forth this invention, what I claim as'neW is- 1. In a temporary binder, the combination of the cover, the binding-strand consisting of a straight portion provided with right-angled end portions curved in the arc of a circle and provided with hooks on their outer faces, open eyelets in the back of the cover through which said curved portions of the binding-strand are adapted to be passed, and closed eyelets in the back of the cover opposite said open eye- In testimony whereof I sign this specifica tion in the presence of two witnesses.
